What’s better than John Williams’ iconic Star Wars music? John Williams’ iconic Star Wars music sung in the style of a cappella by the cast of The Force Awakens with help from Jimmy Fallon and The Roots.

Fallon debuted the a cappella video on Wednesday’s episode of The Tonight Show Starring Jimmy Fallon mere hours before the first official reviews of Star Wars: The Force Awakens arrive online.

The Tonight Show host has had many of the film’s cast members on as guests over the last few weeks, including Harrison Ford, Daisy Ridley, John Boyega, and Adam Driver. Those stars appear in the a cappella video, as do fellow Force Awakens cast members Oscar Isaac, Gwendoline Christie, Carrie Fisher, and even Chewbacca.

Watch the medley of Williams’ score – including the main Star Wars theme and the “Imperial March” – in the video below.
